Calibrachoa plant named ‘USCAL1214-1’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘USCALI214-1’, characterized by its semi-upright to outwardly spreading growth habit; mounded plant habit; freely branching and flowering habit; relatively large coral red-colored flowers; good garden performance; and resistance to  Thielaviopsis .

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCALI214-1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa, botanically known as Calibrachoa sp. and hereinafterreferred to by the name ‘USCALI214-1’.

The new Calibrachoa is a product of a planned breeding program conductedby the Inventor in Hikone, Shiga, Japan. The objective of the breedingprogram is to create new heat-tolerant and disease-resistant Calibrachoacultivars with densely mounding plant habit and numerous and attractiveflowers.

The new Calibrachoa originated from a cross-pollination made by theInventor on Apr. 16, 2003 in Hikone, Shiga, Japan of a proprietaryseedling selection of Calibrachoa sp. identified as code number CJ03-98,not patented, as the female, or seed, parent with a proprietary seedlingselection of Calibrachoa sp. identified as code number CJ03-110, notpatented, as the male, or pollen, parent. The new Calibrachoa wasdiscovered and selected by the Inventor as a single flowering plantwithin the progeny of the stated cross-pollination in a controlledenvironment in Gensingen, Germany on Jun. 4, 2004.

Asexual reproduction of the new Calibrachoa by terminal cuttings in acontrolled environment in Gensingen, Germany since Jun. 5, 2004 hasshown that the unique features of this new Calibrachoa are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar USCALI214-1 has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment and cultural practices such as temperature,daylength and light intensity without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘USCALI214-1’. These characteristics incombination distinguish ‘USCALI214-1’ as a new and distinct cultivar ofCalibrachoa:

-   -   1. Semi-upright to outwardly spreading growth habit; mounded        plant habit.    -   2. Freely branching habit.    -   3. Freely flowering habit.    -   4. Relatively large coral red-colored flowers.    -   5. Good garden performance.    -   6. Resistant to Thielaviopsis.

Plants of the new Calibrachoa can be compared to plants of the femaleparent selection. Plants of the new Calibrachoa differ from plants ofthe female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more upright than and not        as creeping as plants of the female parent selection.    -   2. Plants of the new Calibrachoa and the female parent selection        differ in flower color as plants of the female parent selection        have apricot-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the maleparent selection. Plants of the new Calibrachoa differ from plants ofthe male parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are more outwardly spreading        than and not as upright as plants of the male parent selection.    -   2. Plants of the new Calibrachoa and the male parent selection        differ in flower color as plants of the male parent have red        purple-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the cultivarSunbelchipi, disclosed in U.S. Plant Pat. No. 10,355. In side-by-sidecomparisons conducted in Gensingen, Germany, plants of the newCalibrachoa differed from plants of the cultivar Sunbelchipi in thefollowing characteristics:

-   -   1. Plants of the new Calibrachoa had larger flowers than plants        of the cultivar Sunbelchipi.    -   2. Plants of the new Calibrachoa and the Sunbelchipi differed in        flower color as plants of the cultivar Sunbelchipi had        purple-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of thecultivar Kakegawa S8, disclosed in U.S. Plant Pat. No. 12,508. Inside-by-side comparisons conducted in Gensingen, Germany, plants of thenew Calibrachoa differed from plants of the cultivar Kakegawa S8 in thefollowing characteristics:

-   -   1. Plants of the new Calibrachoa were more upright than and not        as creeping as plants of the cultivar Kakegawa S8.    -   2. Plants of the new Calibrachoa had larger flowers than plants        of the cultivar Kakegawa S8.
